[pstricks] psdot (or Ghostscript) bug

[Faton Berisha]

Hi,

The following minimal example causes an error in GPL Ghostscript 8.54.

\documentclass{article}
\usepackage{pstricks}

\begin{document}
\begin{pspicture}(4,4)
  \psdot[dotstyle=|](2,0)
\end{pspicture}
\end{document}

To be more precise, the ps file (resulting from dvips) seems to be OK, while
ps2pdf results in a crash.

I googled for any references, and I found an exact match at

http://www.ntg.nl/pipermail/ntg-vtex/2003-April/000184.html

The suggested workaround there is replacing pst-dots.pro.

The bug appeared since I updated my MiKTeX installation. Converting ps to
pdf by using Acrobat Distiller seems to work fine.

Any idea?

Kind regards,
Faton Berisha

P.S. Bellow follows the error message produced by GPL Ghostscript 8.54.
